TIFFSetDirectory(3T)		     Image Format Library C++ Reference	Manual

NAME    [Toc]    [Back]

     TIFFSetDirectory, TIFFSetSubDirectory - set the current directory for an
     open TIFF file

SYNOPSIS    [Toc]    [Back]

     #include <tiffio.h>
     int TIFFSetDirectory(TIFF*	tif, tdir_t dirnum)
     int TIFFSetSubDirectory(TIFF* tif,	uint32 diroff)

DESCRIPTION    [Toc]    [Back]

     TIFFSetDirectory changes the current directory and	reads its contents
     with TIFFReadDirectory.  The parameter dirnum specifies the
     subfile/directory as an integer number, with the first directory numbered
     zero.

     TIFFSetSubDirectory acts like TIFFSetDirectory, except the	directory is
     specified as a file offset	instead	of an index; this is required for
     accessing subdirectories linked through a SubIFD tag.

RETURN VALUES    [Toc]    [Back]

     On	successful return 1 is returned.  Otherwise, 0 is returned if dirnum
     or	diroff specifies a non-existent	directory, or if an error was
     encountered while reading the directory's contents.

DIAGNOSTICS    [Toc]    [Back]

     All error messages	are directed to	the TIFFError(3T) routine.

     %s: Error fetching	directory count.  An error was encountered while
     reading the ``directory count'' field.

     %s: Error fetching	directory link.	 An error was encountered while
     reading the ``link	value''	that points to the next	directory in a file.
